Scotland
–
Scotland is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is surrounded by the Atlantic Ocean, with the North Sea to the east. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles, the Kingdom of Scotland emerged as an independent sovereign state in the Early Middle Ages and continued to exist until 1707. By inheritance in 1603, James VI, King of Scots, became King of England and King of Ireland, Scotland subsequently entered into a political union with the Kingdom of England on 1 May 1707 to create the new Kingdom of Great Britain. The union also created a new Parliament of Great Britain, which succeeded both the Parliament of Scotland and the Parliament of England. Within Scotland, the monarchy of the United Kingdom has continued to use a variety of styles, titles, the legal system within Scotland has also remained separate from those of England and Wales and Northern Ireland, Scotland constitutes a distinct jurisdiction in both public and private law. Glasgow, Scotlands largest city, was one of the worlds leading industrial cities. Other major urban areas are Aberdeen and Dundee, Scottish waters consist of a large sector of the North Atlantic and the North Sea, containing the largest oil reserves in the European Union. This has given Aberdeen, the third-largest city in Scotland, the title of Europes oil capital, following a referendum in 1997, a Scottish Parliament was re-established, in the form of a devolved unicameral legislature comprising 129 members, having authority over many areas of domestic policy. Scotland is represented in the UK Parliament by 59 MPs and in the European Parliament by 6 MEPs, Scotland is also a member nation of the British–Irish Council, and the British–Irish Parliamentary Assembly. Scotland comes from Scoti, the Latin name for the Gaels, the Late Latin word Scotia was initially used to refer to Ireland. By the 11th century at the latest, Scotia was being used to refer to Scotland north of the River Forth, alongside Albania or Albany, the use of the words Scots and Scotland to encompass all of what is now Scotland became common in the Late Middle Ages. Repeated glaciations, which covered the land mass of modern Scotland. It is believed the first post-glacial groups of hunter-gatherers arrived in Scotland around 12,800 years ago, the groups of settlers began building the first known permanent houses on Scottish soil around 9,500 years ago, and the first villages around 6,000 years ago. The well-preserved village of Skara Brae on the mainland of Orkney dates from this period and it contains the remains of an early Bronze Age ruler laid out on white quartz pebbles and birch bark. It was also discovered for the first time that early Bronze Age people placed flowers in their graves, in the winter of 1850, a severe storm hit Scotland, causing widespread damage and over 200 deaths. In the Bay of Skaill, the storm stripped the earth from a large irregular knoll, when the storm cleared, local villagers found the outline of a village, consisting of a number of small houses without roofs. William Watt of Skaill, the laird, began an amateur excavation of the site, but after uncovering four houses

History of Scotland
–
The History of Scotland is known to have begun by the end of the last glacial period, roughly 10,000 years ago. Prehistoric Scotland entered the Neolithic Era about 4000 BC, the Bronze Age about 2000 BC, and the Iron Age around 700 BC. Scotlands recorded history began with the arrival of the Roman Empire in the 1st century, North of this was Caledonia, whose people were known in Latin as Picti, the painted ones. Constant risings forced Romes legions back, Hadrians Wall attempted to seal off the Roman south, the latter was swiftly abandoned and the former overrun, most spectacularly during the Great Conspiracy of the 360s. As Rome finally withdrew from Britain, Gaelic raiders called the Scoti began colonizing Western Scotland, according to 9th- and 10th-century sources, the Gaelic kingdom of Dál Riata was founded on the west coast of Scotland in the 6th century. In the following century, the Irish missionary Columba founded a monastery on Iona and introduced the previously pagan Scoti, towards the end of the 8th century, the Viking invasions began. Successive defeats by the Norse forced the Picts and Gaels to cease their hostility to each other and to unite in the 9th century. The Kingdom of Scotland was united under the descendants of Kenneth MacAlpin and his descendants, known to modern historians as the House of Alpin, fought among each other during frequent disputed successions. England, under Edward I, would take advantage of the succession in Scotland to launch a series of conquests into Scotland. The resulting Wars of Scottish Independence were fought in the late 13th and early 14th centuries as Scotland passed back, Scotlands ultimate victory in the Wars of Independence under David II confirmed Scotland as a fully independent and sovereign kingdom. When David II died without issue, his nephew Robert II established the House of Stewart, ruling until 1714, Queen Anne was the last Stuart monarch. Since 1714, the succession of the British monarchs of the houses of Hanover and Saxe-Coburg and Gotha has been due to their descent from James VI, during the Scottish Enlightenment and Industrial Revolution, Scotland became one of the commercial, intellectual and industrial powerhouses of Europe. Later, its decline following the Second World War was particularly acute. In recent decades Scotland has enjoyed something of a cultural and economic renaissance, fuelled in part by a resurgent financial services sector and the proceeds of North Sea oil and gas. Since the 1950s, nationalism has become a political topic, with serious debates on Scottish independence. People lived in Scotland for at least 8,500 years before Britains recorded history, glaciers then scoured their way across most of Britain, and only after the ice retreated did Scotland again become habitable, around 9600 BC. Mesolithic hunter-gatherer encampments formed the first known settlements, and archaeologists have dated an encampment near Biggar to around 8500 BC, numerous other sites found around Scotland build up a picture of highly mobile boat-using people making tools from bone, stone and antlers. The oldest house for which there is evidence in Britain is the structure of wooden posts found at South Queensferry near the Firth of Forth, dating from the Mesolithic period

Monarchy of the United Kingdom
–
The monarchy of the United Kingdom, commonly referred to as the British monarchy, is the constitutional monarchy of the United Kingdom, its dependencies and its overseas territories. The monarchs title is King or Queen, the current monarch and head of state, Queen Elizabeth II, ascended the throne on the death of her father, King George VI, on 6 February 1952. The monarch and his or her immediate family undertake various official, ceremonial, diplomatic, as the monarchy is constitutional, the monarch is limited to non-partisan functions such as bestowing honours and appointing the Prime Minister. The monarch is, by tradition, commander-in-chief of the British Armed Forces, from 1603, when the Scottish monarch King James VI inherited the English throne as James I, both the English and Scottish kingdoms were ruled by a single sovereign. From 1649 to 1660, the tradition of monarchy was broken by the republican Commonwealth of England, the Act of Settlement 1701 excluded Roman Catholics, or those who married Catholics, from succession to the English throne. In 1707, the kingdoms of England and Scotland were merged to create the Kingdom of Great Britain, and in 1801, the British monarch became nominal head of the vast British Empire, which covered a quarter of the worlds surface at its greatest extent in 1921. After the Second World War, the vast majority of British colonies and territories became independent, George VI and his successor, Elizabeth II, adopted the title Head of the Commonwealth as a symbol of the free association of its independent member states. The United Kingdom and fifteen other Commonwealth monarchies that share the person as their monarch are called Commonwealth realms. In the uncodified Constitution of the United Kingdom, the Monarch is the Head of State, oaths of allegiance are made to the Queen and her lawful successors. God Save the Queen is the British national anthem, and the monarch appears on postage stamps, coins, the Monarch takes little direct part in Government. Executive power is exercised by Her Majestys Government, which comprises Ministers, primarily the Prime Minister and the Cabinet and they have the direction of the Armed Forces of the Crown, the Civil Service and other Crown Servants such as the Diplomatic and Secret Services. Judicial power is vested in the Judiciary, who by constitution, the Church of England, of which the Monarch is the head, has its own legislative, judicial and executive structures. Powers independent of government are legally granted to public bodies by statute or Statutory Instrument such as an Order in Council. The Sovereigns role as a monarch is largely limited to non-partisan functions. This role has been recognised since the 19th century, the constitutional writer Walter Bagehot identified the monarchy in 1867 as the dignified part rather than the efficient part of government. Whenever necessary, the Monarch is responsible for appointing a new Prime Minister, the Prime Minister takes office by attending the Monarch in private audience, and after kissing hands that appointment is immediately effective without any other formality or instrument. Since 1945, there have only been two hung parliaments, the first followed the February 1974 general election when Harold Wilson was appointed Prime Minister after Edward Heath resigned following his failure to form a coalition. Although Wilsons Labour Party did not have a majority, they were the largest party, the second followed the May 2010 general election, in which the Conservatives and Liberal Democrats agreed to form the first coalition government since World War II

Queen Victoria
–
Victoria was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. From 1 May 1876, she adopted the title of Empress of India. Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn, both the Duke of Kent and King George III died in 1820, and Victoria was raised under close supervision by her German-born mother Princess Victoria of Saxe-Coburg-Saalfeld. She inherited the throne aged 18, after her fathers three brothers had all died, leaving no surviving legitimate children. The United Kingdom was already a constitutional monarchy, in which the sovereign held relatively little direct political power. Privately, Victoria attempted to influence government policy and ministerial appointments, publicly, Victoria married her first cousin, Prince Albert of Saxe-Coburg and Gotha, in 1840. Their nine children married into royal and noble families across the continent, tying them together, after Alberts death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, republicanism temporarily gained strength and her Golden and Diamond Jubilees were times of public celebration. Her reign of 63 years and seven months is known as the Victorian era and it was a period of industrial, cultural, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire. She was the last British monarch of the House of Hanover and her son and successor, Edward VII, belonged to the House of Saxe-Coburg and Gotha, the line of his father. Victorias father was Prince Edward, Duke of Kent and Strathearn, until 1817, Edwards niece, Princess Charlotte of Wales, was the only legitimate grandchild of George III. Her death in 1817 precipitated a crisis that brought pressure on the Duke of Kent. In 1818 he married Princess Victoria of Saxe-Coburg-Saalfeld, a widowed German princess with two children—Carl and Feodora —by her first marriage to the Prince of Leiningen and her brother Leopold was Princess Charlottes widower. The Duke and Duchess of Kents only child, Victoria, was born at 4.15 a. m. on 24 May 1819 at Kensington Palace in London. Victoria was christened privately by the Archbishop of Canterbury, Charles Manners-Sutton, on 24 June 1819 in the Cupola Room at Kensington Palace and she was baptised Alexandrina, after one of her godparents, Emperor Alexander I of Russia, and Victoria, after her mother. Additional names proposed by her parents—Georgina, Charlotte, and Augusta—were dropped on the instructions of the Dukes eldest brother, George, the Duke of Clarence and the Duke of Kent married on the same day in 1818, but both of Clarences daughters died as infants. Victorias father died in January 1820, when Victoria was less than a year old, a week later her grandfather died and was succeeded by his eldest son, George IV. The Duke of York died in 1827, when George IV died in 1830, he was succeeded by his next surviving brother, William IV, and Victoria became heir presumptive

Rugby union
–
Rugby union, known in some parts of the world simply as rugby, is a contact team sport which originated in England in the first half of the 19th century. One of the two codes of football, it is based on running with the ball in hand. In its most common form, a game is between two teams of 15 players using a ball on a rectangular field with H-shaped goalposts on each try line. Historically an amateur sport, in 1995 restrictions on payments to players were removed, World Rugby, originally the International Rugby Football Board and from 1998 to 2014 the International Rugby Board, has been the governing body for rugby union since 1886. Rugby union spread from the Home Nations of Great Britain and Ireland, early exponents of the sport included Australia, New Zealand, South Africa and France. Countries that have adopted rugby union as their de facto national sport include Fiji, Georgia, Madagascar, New Zealand, Samoa, Tonga, Rugby union is played in over 100 countries across six continents, there are 101 full members and 18 associate members of World Rugby. The Rugby World Cup, first held in 1987, takes place four years with the winner of the tournament receiving the Webb Ellis Cup. The Six Nations Championship in Europe and The Rugby Championship in the Southern Hemisphere are major annual competitions. The origin of football is reputed to be an incident during a game of English school football at Rugby School in 1823. Although the evidence for the story is doubtful, it was immortalised at the school with a plaque unveiled in 1895, despite the doubtful evidence, the Rugby World Cup trophy is named after Webb Ellis. Rugby football stems from the form of game played at Rugby School, Old Rugbeian Albert Pell, a student at Cambridge, is credited with having formed the first football team. During this early period different schools used different rules, with pupils from Rugby. Other important events include the Blackheath Clubs decision to leave the Football Association in 1863, despite the sports full name of rugby union, it is known simply as rugby throughout most of the world. The first rugby football international was played on 27 March 1871 between Scotland and England, by 1881 both Ireland and Wales had representative teams, and in 1883 the first international competition, the Home Nations Championship had begun. 1883 is also the year of the first rugby tournament, the Melrose Sevens. During the early history of union, a time before commercial air travel. The first two notable tours both took place in 1888—the British Isles team touring New Zealand and Australia, followed by the New Zealand team touring Europe, All three teams brought new styles of play, fitness levels and tactics, and were far more successful than critics had expected. After Morgan began singing, the crowd joined in, the first time a national anthem was sung at the start of a sporting event, in 1905 France played England in its first international match

Parliament of the United Kingdom
–
It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom and its seat is the Palace of Westminster in the City of Westminster, one of the boroughs of the British capital, the parliament is bicameral, consisting of an upper house and a lower house. The Sovereign forms the third component of the legislature, prior to the opening of the Supreme Court in October 2009, the House of Lords also performed a judicial role through the Law Lords. The House of Commons is an elected chamber with elections held at least every five years. The two Houses meet in separate chambers in the Palace of Westminster in London, most cabinet ministers are from the Commons, whilst junior ministers can be from either House. The Parliament of Great Britain was formed in 1707 following the ratification of the Treaty of Union by Acts of Union passed by the Parliament of England and the Parliament of Scotland. The UK parliament and its institutions have set the pattern for many throughout the world. However, John Bright – who coined the epithet – used it with reference to a rather than a parliament. In theory, the UKs supreme legislative power is vested in the Crown-in-Parliament. However, the Crown normally acts on the advice of the Prime Minister, the United Kingdom of Great Britain and Ireland was created in 1801, by the merger of the Kingdoms of Great Britain and Ireland under the Acts of Union. The principle of responsibility to the lower House did not develop until the 19th century—the House of Lords was superior to the House of Commons both in theory and in practice. Members of the House of Commons were elected in an electoral system. Thus, the borough of Old Sarum, with seven voters, many small constituencies, known as pocket or rotten boroughs, were controlled by members of the House of Lords, who could ensure the election of their relatives or supporters. During the reforms of the 19th century, beginning with the Reform Act 1832, No longer dependent on the Lords for their seats, MPs grew more assertive. The supremacy of the British House of Commons was established in the early 20th century, in 1909, the Commons passed the so-called Peoples Budget, which made numerous changes to the taxation system which were detrimental to wealthy landowners. The House of Lords, which consisted mostly of powerful landowners, on the basis of the Budgets popularity and the Lords consequent unpopularity, the Liberal Party narrowly won two general elections in 1910. Using the result as a mandate, the Liberal Prime Minister, Herbert Henry Asquith, introduced the Parliament Bill, in the face of such a threat, the House of Lords narrowly passed the bill. However, regardless of the Parliament Acts of 1911 and 1949, the Government of Ireland Act 1920 created the parliaments of Northern Ireland and Southern Ireland and reduced the representation of both parts at Westminster

Horsecar
–
A horsecar, or horse-drawn tram, is an animal-powered tram or streetcar. These were local versions of the lines and picked up and dropped off passengers on a regular route. The horse-drawn streetcar combined the low cost, flexibility, and safety of power with the efficiency, smoothness. The first tram services in the world were started by the Swansea and Mumbles Railway in Wales, fare-paying passengers were carried on a line between Oystermouth, Mumbles and Swansea Docks from 1807. The Gloucester and Cheltenham Tramroad carried passengers although its purpose was freight. Many companies adopted a design of a partly enclosed double-decker carriage hauled by two horses, the last horse-drawn tram was retired from London in 1915. Horses continued to be used for light shunting well into the 20th century, the last horse used for shunting on British Railways was retired on 21 February 1967 in Newmarket, Suffolk. In the United States the very first streetcar appeared on November 26,1832, on the New York, the cars were designed by John Stephenson of New Rochelle, New York and constructed at his company in New York City. The earliest streetcars used horses and sometimes mules, usually two as a team, to haul the cars, rarely, other animals were tried, including humans in emergency circumstances. By the mid-1880s, there were 415 street railway companies in the USA operating over 6,000 miles of track, by 1890 New Yorkers took 297 horsecar rides per capita per year. The average street car horse had a life expectancy of two years. In 1861, Toronto Street Railway horsecars replaced horse driven omnibuses as a public transit mode in Toronto, starting in 1892, electric streetcars emerged in Toronto and by 1894 the TSR stopped operating horsecars in Toronto. The first horse-drawn rail cars on the continent of Europe were operated from 1828 by the České Budějovice - Linz railway, Europe saw a proliferation of horsecar use for new tram services from the mid-1860s, with many towns building new networks. Tropical plantations made extensive use of animal-powered trams for passengers and freight, often employing the Decauville narrow-gauge portable track system. In some cases these systems were extensive and evolved into interurban tram networks. Surviving examples may be found in both the Yucatan and Brazil, since a typical horse pulled a streetcar for about a dozen miles a day and worked for four or five hours, many systems needed ten or more horses in stable for each horsecar. Horsecars were largely replaced by electric-powered streetcars following the invention by Frank J. Sprague of a trolley system on streetcars for collecting electricity from overhead wires. His spring-loaded trolley pole used a wheel to travel along the wire, in late 1887 and early 1888, using his trolley system, Sprague installed the first successful large electric street railway system in Richmond, Virginia

David Livingstone
–
The Nile sources, he told a friend, are valuable only as a means of opening my mouth with power among men. It is this power which I hope to remedy an immense evil and his subsequent exploration of the central African watershed was the culmination of the classic period of European geographical discovery and colonial penetration of Africa. His meeting with Henry Morton Stanley on 10 November 1871 gave rise to the popular quotation Dr. Livingstone and he was the second of seven children born to Neil Livingstone and his wife Agnes. David was employed at the age of 10 in the mill of Henry Monteith & Co. in Blantyre Works. He and his brother John worked twelve-hour days as piecers, tying broken cotton threads on the spinning machines and he was a student at the Charing Cross Hospital Medical School in 1838–40, with his courses covering medical practice, midwifery, and botany. Neil Livingstone was a Sunday school teacher and teetotaller who handed out Christian tracts on his travels as a tea salesman. He extensively read books on theology, travel, and missionary enterprises and this rubbed off on the young David, who became an avid reader, but he also loved scouring the countryside for animal, plant, and geological specimens in local limestone quarries. Other significant influences in his life were Thomas Burke, a Blantyre evangelist. At age nineteen, David and his left the Church of Scotland for a local Congregational church, influenced by preachers like Ralph Wardlaw. For Livingstone, this meant a release from the fear of eternal damnation, Livingstones reading of missionary Karl Gützlaffs Appeal to the Churches of Britain and America on behalf of China enabled him to persuade his father that medical study could advance religious ends. Livingstones experiences in H. Monteiths Blantyre cotton mill were important from ages 10 to 26. To enter medical school, he required some knowledge of Latin, a local Roman Catholic named Daniel Gallagher helped him learn Latin to the required level. Later in life, Gallagher became a priest and founded the third oldest Catholic Church in Glasgow, St Simons, a painting of both Gallagher and Livingstone by Roy Petrie hangs in that churchs coffee room. In addition, he attended divinity lectures by Wardlaw, a leader at this time of vigorous anti-slavery campaigning in the city, shortly after, he applied to join the London Missionary Society and was accepted subject to missionary training. He qualified as a Licentiate of the Faculty of Physicians and Surgeons of Glasgow on 16 November 1840, Livingstone hoped to go to China as a missionary, but the First Opium War broke out in September 1839 and the LMS suggested the West Indies instead. In 1840, while continuing his studies in London, Livingstone met LMS missionary Robert Moffat, on leave from Kuruman. He was excited by Moffats vision of expanding missionary work northwards, buxtons arguments that the African slave trade might be destroyed through the influence of legitimate trade and the spread of Christianity. Livingstone, therefore, focused his ambitions on Southern Africa, during this time, Livingstone was attacked by a lion while staying in an African village, trying to defend the villages sheep from the animal

Henry Morton Stanley
–
Sir Henry Morton Stanley GCB was a Welsh-American journalist and explorer who was famous for his exploration of central Africa and his search for missionary and explorer David Livingstone. Upon finding Livingstone, Stanley reportedly asked, Dr. Livingstone, Henry Stanley was born in 1841 as John Rowlands in Denbigh, Denbighshire, Wales. His mother Elizabeth Parry was 18 years old at the time of his birth and she abandoned him as a very young baby and cut off all communication. Stanley never knew his father, who died within a few weeks of his birth, there is some doubt as to his true parentage. As his parents were unmarried, his birth certificate describes him as a bastard, the boy John was given his fathers surname of Rowlands and brought up by his maternal grandfather Moses Parry, a once-prosperous butcher who was living in reduced circumstances. He cared for the boy until he died, when John was five, Rowlands stayed with families of cousins and nieces for a short time, but he was eventually sent to the St. Asaph Union Workhouse for the Poor. The overcrowding and lack of supervision resulted in his being frequently abused by older boys, historian Robert Aldrich has alleged that the headmaster of the workhouse raped or sexually assaulted Rowlands. When Rowlands was ten, his mother and two half-siblings stayed for a short while in this workhouse, but he did not recognize them until the headmaster told him who they were, Rowlands emigrated to the United States in 1859 at age 18. He disembarked at New Orleans and, according to his own declarations, became friends by accident with Henry Hope Stanley and he saw Stanley sitting on a chair outside his store and asked him if he had any job openings. He did so in the British style, Do you need a boy, the childless man had indeed been wishing he had a son, and the inquiry led to a job and a close relationship between them. Out of admiration, John took Stanleys name, later, he wrote that his adoptive parent died two years after their meeting, but in fact the elder Stanley did not die until 1878. This and other discrepancies led John Bierman to argue that no adoption took place, Tim Jeal goes further, and, in Chapter Two of his biography, subjects Stanleys account in his posthumously published Autobiography to detailed analysis. Stanley reluctantly joined in the American Civil War, first enrolling in the Confederate Armys 6th Arkansas Infantry Regiment, after being taken prisoner at Shiloh, he was recruited at Camp Douglas, Illinois by its commander Colonel James A. He joined the Union Army on 4 June 1862 but was discharged 18 days later because of severe illness, after recovering, he served on several merchant ships before joining the US Navy in July 1864. He became a keeper on board the USS Minnesota, which led him into freelance journalism. Stanley and a junior colleague jumped ship on 10 February 1865 in Portsmouth, Stanley was possibly the only man to serve in the Confederate Army, the Union Army, and the Union Navy. Following the Civil War, Stanley became a journalist in the days of frontier expansion in the American West and he then organised an expedition to the Ottoman Empire that ended catastrophically when he was imprisoned. He eventually talked his way out of jail and received restitution for damaged expedition equipment, an assignment to report on the Spanish Civil War followed

Ujiji
–
Ujiji is the oldest town in western Tanzania, located about 6 miles south of Kigoma. In 1900, the population was estimated at 10,000, part of the Kigoma/Ujiji urban area, the regional population was about 50,000 in 1978. Ujiji is the place where Richard Burton and John Speke first reached the shore of Lake Tanganyika in 1858. It is the site of the meeting on 10 November 1871 when Henry Stanley found Dr. David Livingstone. I see him. ’ and off he darted to meet him, the American flag at the head of the caravan told of the nationality of the stranger. There is also a modest museum, there is a former slave route near the market. In 1878, the London Missionary Society established their first missionary post on the shore of Lake Tanganyika at Ujiji, some in Burundi claim the location of the famous meeting is a few miles south of the capital Bujumbura. However the Livingstone-Stanley Monument in Mugere actually marks a visit the two men made 15 days later on their joint exploration of northern Lake Tanganyika, initially an Arab slave trade route that began in the 1850s, formerly known as Ugoi

Lake Tanganyika
–
Lake Tanganyika is an African Great Lake. It is the second oldest freshwater lake in the world, second largest by volume, the lake is divided among four countries – Tanzania, Democratic Republic of the Congo, Burundi, and Zambia, with Tanzania and DRC possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean, the name apparently refers to Tanganika, the great lake spreading out like a plain, or plain-like lake. Lake Tanganyika is situated within the Albertine Rift, the branch of the East African Rift. It is the largest rift lake in Africa and the second largest lake by volume in the world and it is the deepest lake in Africa and holds the greatest volume of fresh water, accounting for 18% of the worlds available fresh water. It extends for 676 km in a general direction and averages 50 km in width. The lake covers 32,900 km2, with a shoreline of 1,828 km, a depth of 570 m. It holds an estimated 18,900 cubic kilometres and this is equivalent to about 16% of all fresh water on Earth. The catchment area of the lake is 231,000 km2, two main rivers flow into the lake, as well as numerous smaller rivers and streams. There is one major outflow, the Lukuga River, which empties into the Congo River drainage, the major river flowing into the lake is the Ruzizi River, formed about 10,000 years ago, which enters the north of the lake from Lake Kivu. The Malagarasi River, which is Tanzanias second largest river, enters the east side of Lake Tanganyika, the Malagarasi is older than Lake Tanganyika and, before the lake was formed, directly drained into the Congo River. Apparently it has rarely in the past had an outflow to the sea and it has been described as practically endorheic for this reason. The lakes connection to the sea is dependent on a water level allowing water to overflow out of the lake through the Lukunga into the Congo. Due to the tropical location, it has a high rate of evaporation. Thus it depends on a high inflow through the Ruzizi out of Lake Kivu to keep the lake high enough to overflow. Signs of ancient shorelines indicate that at times Tanganyika may have been up to 300 m lower than its present surface level, even its current outlet is intermittent and may not have been operating when first visited by Western explorers in 1858. Lake Tanganyika is an ancient lake and its three basins, which in periods with much lower water levels were separate lakes, are of different ages. The central began to form 9—12 million years ago, the northern 7—8 mya, there are several islands in Lake Tanganyika

Asbestos
–
They are commonly known by their colors, as blue asbestos, brown asbestos, white asbestos, and green asbestos. It was used in applications as electrical insulation for hotplate wiring. When asbestos is used for its resistance to fire or heat and these desirable properties made asbestos very widely used. Prolonged inhalation of asbestos fibers can cause serious and fatal illnesses including cancer, mesothelioma. Concern of asbestos-related illness in modern times began in the 20th century, by the 1980s and 1990s, asbestos trade and use were heavily restricted, phased out, or banned outright in an increasing number of countries. S. History and a much lesser legal issue in most other countries involved, asbestos-related liability also remains an ongoing concern for many manufacturers, insurers and reinsurers. Asbestos derives from the ancient Greek ἄσβεστος, meaning unquenchable or inextinguishable, the word is pronounced /æsˈbɛstəs/, /æzˈbɛstəs/ or /æzˈbɛstɒs/. Six mineral types are defined by the United States Environmental Protection Agency as asbestos including those belonging to the serpentine class, all six asbestos mineral types are known to be human carcinogens. The visible fibers are themselves composed of millions of microscopic fibrils that can be released by abrasion. Chrysotile is the member of the serpentine class. 12001-29-5, is obtained from rocks which are common throughout the world. Its idealized chemical formula is Mg34, chrysotile appears under the microscope as a white fiber. Chrysotile has been used more than any type and accounts for about 95% of the asbestos found in buildings in America. Chrysotile is more flexible than amphibole types of asbestos, and can be spun, the most common use was corrugated asbestos cement roofing primarily for outbuildings, warehouses and garages. It may also be found in sheets or panels used for ceilings and sometimes for walls, chrysotile has been a component in joint compound and some plasters. Amosite, crocidolite, tremolite, anthophyllite and actinolite are members of the amphibole class, one formula given for amosite is Fe7Si8O222. Amosite is seen under a microscope as a grey-white vitreous fiber and it is found most frequently as a fire retardant in thermal insulation products, asbestos insulating board and ceiling tiles. 12001-28-4, is the form of the amphibole riebeckite, found primarily in southern Africa
